comment How to describe the performance requirements for a PC game?
To that end maybe the answer is for software vendors (ex: Steam, Origin) to start listing games with similar requirements. That way the consumer can say "hey, watch_dogs runs great on my computer. It looks like Titanfall will run just fine" (Just an example, I own neither game and don't know their actual requirements)

comment What does a matrix represent?
A lot of times they are applied to an object or the viewport as a whole (thats how you get your ortho vs perspective views)

comment Would A* or Dijkstra be more proper for a grid-based tactics game?
If you have a heuristic in your computation you can start with the basic weight function, but afterwords you can modify it to make your AI do fun things like swarm to the sides of the enemy rather than head on. A* wins all the way.

comment Defining an OpenGL unit
For the sake of ease of learning I recommend sticking with these until you get more used to working with OpenGL. They are older and therefore have more tutorials behind them. Plus, they are easier to understand for someone just starting out (no matrix math involved).

comment Defining an OpenGL unit
*_x and *_y happen to be values that you can pick. If I want my coordinates on screen to be x:(-100,50),y:(-60,20),z(-10,10) I would call glOrtho(-100,50,-60,20,-10,10); At that point its a matter of preference
